AS Configuration Timing
Table 1-68: AS Timing Parameters for AS ×1 and ×4 Configurations in Arria V Devices
e minimum and maximum numbers apply to both the internal oscillator and CLKUSRwhen either one is used as the clock source for device
configuration.
e tCF2CD, tCF2ST0, tCFG, tSTATUS, and tCF2ST1 timing parameters are identical to the timing parameters for passive serial (PS) mode listed in PS
Timing Parameters for Arria V Devices table. You can obtain the tCF2ST1 value if you do not delay configuration by externally holding nSTATUSlow.
